Katrina thinks she's just a normal everyday girl. Likes to go down to the beach at night everynight. Just normal right? Till the day everything goes down hill and Katrina's life gets turned around for the worse.
She finds out she's a daughter of the moon goddess and of the sea god, she also finds out that her best friend sense she can remember is her sister.
Now Hades, god of the underworld is out to get her. He sends people called *Shadows* or *Hunters* out to get her. Then her sister is taken and she needs all the help she can get to get her sister back.
